SYSVAR, cont.
Remarks, cont. 36: Print changes of program modes (Set or Read)
This parameter is used with the Fingerprint debugger and controls whether
changes of program modes should be printed to the Debug Standard
Out port (see DBSTDIO).
The options are:
0 = Disable printout (default)
1 = Enable printout
37: Set Minimum Gap Length (Set or Read)
The media may have perforations or marks that not are intended to be
interpreted as gaps or black marks by the LSS. Using this SYSVAR
parameters, it is possible to make the LSS ignore gaps or marks that are
shorter that a specifi ed value. (In this context, long and short are related
to the media feed direction.) The minimum gap length is specifi ed in dots
within a range of 1-32. Default value is 1 mm (0.039 inches). Note that
SYSVAR(37) affects PRINTFEED and FORMFEED. For TESTFEED,
see SYSVAR(38).
38: Set Equal Safe for TESTFEED (Set or Read)
This parameter is similar to SYSVAR(37), but it only affects how TESTFEED
will detect gaps and black marks. SYSVAR(38) specifi es how many
consecutive detections of a gap or mark the LSS will have to make before
the fi rmware registers it as a gap or mark. The allowed range is 0-255
and the default value is 6.
39: Enable/Disable Slack Compensation (Set or Read)
Label slack compensation is a method of eliminating slack in the belts
after having fed the media back. At a negative FORMFEED, the printer
will pullback the media slightly more than specifi ed by the FORMFEED
statement and the feed the media forward the same distance. For example, if
FORMFEED -100 is specifi ed, the printer will pull back the media -112 dots
and then feed the media forward +12 dots to take out the slack.
In some applications, this method could be inconvenient, so it is possible
to enable/disable it.
The options are:
0 = Disable slack compensation
1 = Enable slack compensation (default)
40: Not Implemented
41: “Next label not found” at Predefi ned Feed Length (Set or Read)
The automatic detection of the error condition “Next label not found” (error
1031) by the label stop sensor can be overridden by specifying a fi xed length
in dots. The length should preferably correspond to at least the distance
between the tops of two consecutive labels. During printing, error 1031
occurs if the media does not come loose from the core (media glued to core)
or if a label is missing on the liner. Especially useful for short labels (10–40
mm/0.4–1.5 inches long). Default value is 0.
